1. Walk through the space

A cleanup technician maps the droppings, stains and damaged insulation in attics, lofts or on rooftops.

Guano, soiled insulation and nesting debris are removed by hand or with HEPA-filtered tools and sealed in heavy bags.

Guano Cleanup Frequently Asked Questions in Eureka Valley, San Francisco, CA

How much does guano removal cost?

It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.

What is histoplasmosis?

Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.

Can guano get into ductwork or vents?

Yes, if birds or bats roost near vents or intakes, droppings and dust can enter air paths. Cleanup may include treating vent openings and nearby surfaces.

What rules apply to guano cleanup in California?

Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.

What should I do first if I find guano?

Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call Eureka Valley Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

Why shouldn't guano be swept or blown?

Dry droppings turn to fine dust that floats in the air and can carry fungal spores. Sweeping or blowing sends that dust into the air where you breathe it. Wetting first keeps particles on the surface.

Found bat or bird droppings in Eureka Valley, San Francisco, CA?

Guano dust is easy to breathe in, so protection and containment come first.
